Largest Palindromic Substring

MediumPython

Problem

Find the largest palindromic substring in a given string. Implement longest_palindrome(s) to return the longest contiguous substring that reads identically forward and backward. If multiple substrings have the same maximum length, return the leftmost one. The input is a string, and the output is a string.

Constraints

0 <= len(s) <= 1000
s contains printable characters
Return the leftmost substring when multiple longest palindromes have equal length
